Gwyneth Paltrow may be hanging up her Pepper Potts hot pants.
The Oscar winner reveals she may not be back for the Avengers sequel.
"I don't know," she exclusively told E! News at the Toronto Film Festival premiere of her sex addiction dramedy, Thanks For Sharing. "I'm getting old for this s--t, you know what I mean?"
Paltrow originated the role in the first Iron Man movie. She played her again in Iron Man 2 and the recently wrapped third installment of the franchise.
While the 39-year-old mom of two may feel too old for the superhero sequel, she certainly isn't showing it.
In Thanks For Sharing, Paltrow plays a woman dating a sex addict (Mark Ruffalo). In one scene, she shows off her incredible body while giving Ruffalo a lap dance in some incredibly sexy black lingerie. At the premiere, she stunned in a black Tom Ford dress.
"They called me up and they sent me the script and I read it and it was really really good," Paltrow said of the indie.
She signed on after meeting first-time director Stuart Blumberg. "And it was just like a couple of weeks in New York in the fall and I could bring my kids," Paltrow said. "I was like, 'OK, let's do it.'"
Not like she didn't bring the kids to the Avengers and Iron Man sets.
Paltrow laughed, "They like it better when I do that than sex addiction movies."
And speaking of Avengers, it was Hulk mash-up at the Sharing premiere when Ruffalo stopped to chat with the movie's executive producer and former green superhero, Edward Norton.
There's obviously no hard feelings between the two. Ruffalo even told us he considers Norton his "hero."
